Electronic Speckle Pattern Interferometry ESPI is an optical technique allowing full field measurement of surface dis-placement. Three decades have passed since Butters and Leendertz published their ground-breaking articles on electronic speckle-pattern interferometry (ESPI). Electronic speckle pattern interferometry is an attractive technique for the characterization of materials at elevated temperatures. 1.

Electronic-speckle-pattern-interferometry (ESPI) determines the difference between two small deformation states of the same inspected object.

Electronic Speckle Pattern Interferometry

A better approach is to use Electronic Speckle Pattern Interferometry (ESPI).
